'UNITED STATES PATENT Ormea.`

ORESTFS SAMPSON, OF PETERSBURG, ILLINOIS.

Specification forming part of Letters Patent No 112,079, dated February 21,1571; antedated February 20, 1871.

To @ZZ whom, t may concern:

Beit known that I, Onnsrns SnMPsoN, of Petersburg, in the county of Menard and State of Illinois, have invented certain Improvements in Combined Gang-Blows and Cultivators, oi' which the following is a specification, reference being had to the accompanying drawings.

My invention relates to a combined gangplow and cultivator; and it consists in a jointed wheeled frame of peculiar construction, provided with interchangeable plows and cultivator-shovels, as hereinafter described.

Figure 1 is a top plan view of my device arranged as a gang-plow; and Fig. 2 a longitudinal vertical section of the same, taken on the line wx of Fig. 1. Fig. 8 is a top plan view of the forward and pivoted portion of the frame detached, and cultivator shovels substituted for the plows shown therein in Fig. l; and Fig. fi is a side view of one of the detachable rock-shafts having the shovels attached.

My machine consists, mainly7 of an axle, A, mounted in two driving wheels, a, and having secured rigidly to it a rectangular frame, B, the side rails of which extend forward ot' the axle, and have pivoted to and between them a smaller rectangular frame, D, which is free to rock upon its pivots c, and to which the plows and shovels are attached, as hereinafter described.

On the frame B, in rear of the axle, is mounted a longitudinal seat, G, for the driver, this seat being so located and the frame B so balanced that when the driver sits upon the forward end of the seat, the frame will maintain a horizontal position, or thereabout, but that when he moves backward, his weight will depress the rear end of frame B, and thereby elevate its arms b and raise the frame D, as shown in dotted lines in Fig. 2.

Upon the frame D is placed the tongue G of the machine, hinged or otherwise attached to the rear bar of said frame, and extending forward between two arms, d, on the front bar of the same, said arms being provided with a series of holes, and the tongue with a corresponding hole, so that by means of a pin inserted therein the forward end of the tongue may be adjusted in height, a-s required. The under side of the frame D, on

pair of boxes or bearings, e, by means of which two bars, E, each carrying a plow, H, may be secured to the frame, as in Figs. l and 2, the ends of the bars being provided with necks which enter the boxes, and which are flattened upon their upper sides, so that when secured in place the bars are held from turning, and thereby the plows maintained in p0- sition.

Vhen thus arranged, the device forms a gang-plow, upon which the operator can ride and regulate the depth of the plows, or throw them out of the ground by merely moving for-y ward or back upon his seat.

Wvhen the machine is to be used as a culti vator, the boxes e are loosened, and the bars E, carrying the plows, removed,and rock-shafts F, having round journals, and each carrying two shovels, I, as shown in Fig. 4, are substituted therefor, as shown in Fig. 3. The for- -ward shovels are set inward and the rear shovels outward, in the manner common in straddle-row cultivators, and each of the rocklshafts are provided with an operating-handle, J, as shown in Figs. 3 and 4, and the handles of the two shafts are connected by a rod or link, m, attached to eyes thereon, as shown in Fig. 3, so that by operating either handle both pairs of shovels may be thrown from' side to side, as necessary, in addition to which they may-also be raised and lowered in the saine manner as the plows by the weight of the driver.

If desired, the boxes e may be made adjustable laterally/,to provide for setting the plows or shovels at different distances apart, as occasion may require.

By these means I provide a very simple and efficient implement adapted to all the ordinary uses of the plow, and also of a cultivator, and one that can be operated with much less labor than is generally required in gang-plows of thel ordinary construction, and

each side of the tongue, is provided with a.

which costs t0 the farmer but little more than the adjustable tongue Gattaeheinand adapted either one 0f the said implements as ordinarily to carry either plows or cultivators, whereby made. the implement is fitted to be used either as a Having thus described my invention, what gang-plow or a eultivator, as set forth.

I claim is- ORESTES SAMPSON.

mounted on Wheels a, and provided with the W. IRA ALLEN,
